 · A low-value byproduct of the coal mining process is proving highly effective at helping reclaim the land and water used in mining, University of Alberta research shows. Nano humus, a substance extracted from coal mine deposits and then crushed to a black, powdery material, has "outstanding physical and chemical properties" that remove heavy ...

Coal slurry is a waste product of coal mining. Components in slurry come from the coal and the chemicals used in processing it. The washing or purifying process reduces pollution -causing contaminants in the coal, but these impurities then become part of the slurry. The composition of coal slurry varies depending on the coal and the processing ...

Waste Management facilitates recycling and re-utilization of fly ash and other CCPs for a variety of building products and construction materials. We help our customers generate income and divert CCPs from local landfills, which protects the environment by reducing demand for manufactured materials.

Coal waste in Pennsylvania. Coal refuse (also described as coal waste, coal tailings, waste material, culm, boney, or gob) is the material left over from coal mining, usually as tailings piles or spoil tips. For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially ...

There are several approaches for the reuse of these waste products, especially in relation to clay minerals that can induce pozzolanic reactions of special interest in the cement industry. In the present paper, scientific aspects are discussed in relation to several inert coal-mining wastes and their recycling as alternative sources of future ...

The coal mining waste has been converted into wealth and played more and more important roles in many fields. The practice indicated that these patterns can be applied in other coal mines ...

 · The coal mining industries generate a considerable volume of pyrite-rich tailings (FeS 2).However, pyrite waste is potentially reusable. Therefore, this study aimed to evaluate possible ways of waste and effluent valorization that are generated during the processing of coal mining pyrite (R1).

 · Focusing on production from coal mines and waste products has the added advantage of potentially creating new, good-paying jobs in places hard-hit by the move from fossil fuels to renewables, said ...

The Environmental Protection Agency (EPA) describes coal refuse as waste products of coal mining, physical coal cleaning, and coal preparation operations containing coal, matrix material, clay, and other organic and inorganic material. Others have described coal refuse as a by-product of coal mining

 · Reuse and recycling can also reduce the environmental effects of coal production and use. Land that was previously used for coal mining can be reclaimed and used for airports, landfills, and golf courses. Waste products captured by scrubbers can be used to produce products such as cement and synthetic gypsum for wallboard.

 · Understanding Mining Waste Management and Disposal Methods. Mining produces a lot of waste which needs to be handled properly. Improper mining waste disposal will lead to air, soil, and water pollution. Different types of mining include landfill mining, coal mining, oil and gas extraction, metal, and non-metal ore mining.
